Abstract
The present disclosure provides a dual-frequency antenna and an electronic device, belonging to the field of communication technologies. The dual-frequency antenna of the present disclosure includes a first antenna unit and a second antenna unit arranged opposite to each other, and a filter unit arranged between the first antenna unit and the second antenna unit. The operating frequency of the first antenna unit is a first frequency band, the operating frequency of the second antenna unit is a second frequency band, the filter unit is arranged to reflect electromagnetic waves in the first frequency band and transmit electromagnetic waves in the second frequency band. The first antenna unit is arranged to receive electromagnetic waves in the first frequency band and reflect the received electromagnetic waves in the first frequency band by the filter unit. The second antenna unit is arranged to receive the electromagnetic waves in the second frequency band that have passed through the filter unit and reflect the electromagnetic waves in the second frequency band.
